Roller Coasters are fun because they give you that thrill. Even though the lines are super long, the roller coaster makes up for it because it's usually longer than a minute or shorter but the scenery is nice. Now with the calmer and slow ride are also fun but I feel like those are more after when you eat so you don't throw up. Although people say it just depends on the person and how they handle it but I think to just play safe you do a calm ride. Not only that you get one ride down and out of the way. But back to the rollercoasters, it's just fun in general. Especially when it's themed. I think a theme park that has equal amounts of calm and thriller is Knott's Berry Farm because it has both mixers and not only that it has a variety of food options whether you want to eat a lot or a little.
